If you're using Realtek Audio Manager [located in the Notification Icon Tray] you can search for Volume Control and scroll through till you find Adobe Flash Player. Make sure that sound is all the way up.
Adobe Flash player is the way to view videos on youtube, etc. And your games don't use Adobe Flash player.
Hope this helps someone even though the thread is really old!
So I went from having a whisper of a sound to only having system sounds (now those are pleasantly loud). I can see on the Volume mixer that it's registering that something's playing on youtube, but there's nothing coming out of the built-in speakers. Ideas?
so, I know this is seriously outdated and all but I had been having the same problems and none of the solutions I found worked, I did 2 clean installs of windows to fix it which worked the 1st time but not the 2nd time, the fix that worked for me was to go in to HD audio manager and switch to 5.1 which had been changed for some reason
Try This It Might Try Turning the Dynamic Boost option to max

This is how I fixed my problem:
Right click on the speaker in taskbar (the one from windows, not another one)
Clicked on "Volume control options"
Checked all the boxes: "All the devices currently playing sound", "The default communication device", Sound devices: "Speakers"
Pressed OK and now everything is WAY louder, like it used to be. When volume is at 20%, it is as loud as 100% while having the problem.
I know this is OLD OLD OLD but noting here worked for me but the following did help . . .
In windows7 go to Sounds > go to Playback
Pick speakers as output device
Go to Properties > At Levels (check it's at 100%)
Go to Enhancments > enable Loudness Equalisation > Click [Apply]
Should be much louder now...
